s claims.

This invention relates to an improved container for the storage andshipment of liquids.

A further object of the invention is that of furnishing a unit of thischaracter ideally suited for the storing and dispensing of carbonated orother liquids having relatively high internal pressure.

A still further object is that of providing-a container from whichliquids may readily be dis- |0 pensed and which container may have asealing means associated withY it to assure of the maintenance of thestored liquid without spillage, deterioration or loss of carbonated gas.

Another object is that of providing a container 1b which will notcontaminate or transmit by odor or taste any objectionablecharacteristics to the liquids contained therein With these and otherobjects in mind, reference is had to the attached sheet of drawings.

m illustrating one practical embodiment of the invention, and in which:

Fig. 1 is a plan view of the container with certain of the parts brokenaway to show underlying construction;

Fig. 2 is a sectional view taken along the lines 2-2 and in thedirection of the arrows of Fig. 1;

and

Fig. 3 is a perspective view of the top of a container as constructed inaccordance with the a teachings of my invention.

This application is a continuation in part of my applicationv Serial No.92,982, led July 28, 1936.

In the illustrated. embodiment. I have shown my invention applied to apreferredform or arrangement for making a high-pressure resistingbeverage container and -it is understood that this islonly illustrative,that certain deviations, substitutes/or mechanical equivalents, or usefor non-carbonated or non-pressureV beverages 4or other/liquid orviscous materials, would not deviate from the spirit of the invention.'

Thus a illustrates the outer housing wall or body of thevprimarycontainer structure. 'I'his a wall is preferably made of a plurality ofplys or a number of convolutions of suitable paper rolled upon a mandrelwith a suitable adhesive between the layers.

The ends of the container are formed by paper 50 discs b and c separatedAand secured together by a stiffening filler plate or `disc d adhesivelyattached to them. Each of the end discs b is provided wi'th an annularperipheral flange k which contacts tightly with the inner surface of thecylindrical wall a of the container and to which it is secured bysuitable adhesive. As will appear from the drawing, said iiange 7cextends outwardly or toward the ends of the container. The-inner coverdiscs c are similarly provided with inwardly extending annular flangesll similarly se- Il cured to the inner wall a of the container. 'Iheembodied means for further securely fastening the end members to thecylindrical container and integrating same therewith comprises theprovision of cylindrical extensions at either end of the 10 side wall aof the container, which extensions are curled, clamped or folded andformed .over and inwardly along the inner surface of the anges Ic, 7cand are secured thereto by-suitable adhesive previously applied to thesurfaces to be l5 secured. Thus-the flanges 1c, lc of the end pieces bare adhesively attached to the inner walls of the container which are inturn folded over and inwardly and preferably the inwardly folded ends ofsaid container a extend to meet or lie against the outerlgsurfaces ofthe discs b. The construction, as shown and described, is useful inproviding a substantially strong and rigid structure which can bereadilyv formed with simple dies or other well 'known' methods andreadily assembled. 25

It will be understood, however, that my invention is not limited to anyparticular physical construction of the end closures ofthe container, aswill be clear from the appended claims.

It is to be noted that one end, constitutingv the bottom of the`container structure is preferably made imperforate, and the opposite endassembly, dening the top, is preferably made with an opening for fillingand emptying the container. Thus the upper vend p ieces b and c, withthe stlffening plate d, before being insertedv and secured to thetubularbody portion a have attached, the neck or spout member'e. Thismember may be a molded compound and mechanical equivalents may beemployed in the formof a o flanged member. with a threaded neck portion,embracing the end parts b and c and secured with a locking nut.Regardless of the material and particular conflguratiomv of-this member,it will be observed that in eifect the stiifening plate d' 45 providesan enlarged flange 'portion forminga part ofthe member.

After the body portion of the container structure is completelyassembled, with ends inserted and secured with suitable adhesive and theends of the body portionl a formed and crimped or flanged over the edgesof the end pieces b and b, the container housing form is thoroughlydried to remove all moisture-from 'the adhesive used.

The fibrous structure is now used as a -form to supportv within it, animpervious, tasteless, odorless, non-toxic pressure-resisting, elasticand exible compound, which, when set, constitutes a secondary water and.gas impervious' container within the brous form structure, asillustrated, at h.

I have discoveredthat materials which have a permeation or impregnationcharacteristic property, as a rule are unsuited as a lining material toresist or sustain pressure. I have also discovered that materials insoluble form, after the evaporation of the solvent, usually leave voidsIwhen the compoundhas dried or-set; such voids forming minute channelsfor `the passage and escape of the retained pressure. Such materials aswaxes of. all kinds, synthetic rubber compounds, synthetic resinvarnishes and lacquers, commonly considered to be impervious areentirely unsuited for resisting air, gas or liquids under pressure; Thisis; :partly due to the lack of density of the structure or the voids'between crystals. I have found that all soluble compounds, used inliquid state, when dry, retain a considerable quantity of residualsolvent for a long time, which imparts to beverages with which it comesinto contact, detrimental characteristics either in the form of taste orodor or lchanges'o. temperature and rough handling. It

is of course obvious that if such a film were used f to confine gases orliquids -and fractured,` the gases or liquids, especially if underpressure, would readily escape.

Moreover, inlorcier for the rosin to be employed as a liner material inconnection with containers for carbonated liquids it must be free fromoils or soft gums containing oils, which would have. a deleteriouseffect upon the carbonation or 4otherwise detrimentally affect thecontained liquid. I have also discovered that the objections are notsimply overcome by 'employing conventional plasticizing materials, inthat they either reduce the melting point of the rosin compound and/orimpart to it an undesired taste or odor. 1 hare, however, found that Ican plastlcize a'.:.l compound with a rosin a suitable quantity ofpolymerized hydrocarbon essentially of straight chain structure.` Inother words, there `is included polymerizd isobutylene, which is .af

polymerized product produced from a hydrocarbon derived for example fromthe refining of petroleum'.

Such a compound results'in a product which These characteristics may becontrolled within any desired limits,- depending upon the quantity ofthe hydrocarbon polymer compounded with -pound is easily accomplished bymelting the compound andlpouring it into the paper container form andimmediatelyvemptying it. A thin dense glazed iilm h will adhere to theinner surface of the container, forming a quasi glasslike innerimpervious container within the form housing which imparts the necessaryform, strength and structure, this inner container also possessing greatelasticity. Since this plasticized compound has no penetration,saturation or impregnation properties, and' is poured or ap plied intothe form in a molten state and emptied immediately in the same manner inwhich slush castings are molded, it is obvious that the impervious orsecondary container is a molded impervious container itself, whichacquires support from the rigidifying outer container.

Thus, among others,'the several objects of the invention as specicallyaforenoted are achieved.-

It will be obvious'that numerous changes in construction andrearrangements of the parts might be resorted to without .departing fromthe spirit of the invention as defined by the claims, which are: Y
